Application filed May 26, 1916. Serial No. 100,009.

To. all whom it may concern Be it known that I, ROBERT L. Donan, a

citizen of the United States of America, and

a resident-otChicago county of Cook, and

State of Illinois have invented certain new and useful linprovementszin Oil-Burners, of

which the following isa specification.

Themain objects ofthis invention are to provide an improved-form of combined gas generator and burner for utilizing heavy fuel oils for heating and cooking; to pro- I vide an improved arrangement of-the parts whereby the device is particularly suitable for use in the fire box of coal and wood stoves and ranges; to provide an improved.

form-of burner;.to provide an improved arrangement of the generator; to provide improved means for simultaneously controlling the flow'ofoil to the generator and the tlow of vapor from'the generator to the mixing chamber; and to provide improved means for controlling the admission of gas to the 'An illustrative embodiment of this invention is shownin the'accompanying drawings,-in which: K Figure l'is a perspective view of the complete'devicel l ig. 2 is an enlarged sectional plan jofftlie upper-burner some of the parts below being omitted for the sake of clearness Fig. 3 is a side elevation ot one of the mixing chambers. Fig. i is a sectional view of the same taken on the line .\i\ of Fig.

Fig. 7 is an enlarged horizontal sectional detail of the oil supply fitting and the main generatortube. Fig. 8 is a longitudinal SBCtlODtll' elevation oi" the arrangemerit illustrated in Fig. 1. Fig. l) is an enand their respective.generating means 5 and '50 larged transverse sectional elevation of the device, taken in the opposite direction from that of Fig. 5.-

In the construction shown in the drawings, the device comprises a pair otstanda'rds 1 andQ upon which are mounted atop or main burner-3, a side or oven burner 4,

6. The parts are all arranged compactly upon the standards 1 and 2.:so that the device is particularly suitable tor arrangement within-the fire box of any of the usual coal or wood ranges whereby the upper burner direct at the end thereof which is roasting.

The top or general cooking burner 3 is in the form of a tubular oblong loop having a plurality of slots 7 Cfl lti lll the upper part' thereof, through which the gas is emitted to be burned. A manifold in the form of a U- shaped pipe or tube 8 depends from the under side of the burner 3 and has the ends thereof connected to opposite sides. A oonduit 0 is attached at the bend of the U- shaped pipe8 as shown in Fig. 2 and is bent back upon itself the same as shown in Fig. 8, and connects with the mixing chamber 10,

through which the gas is delivered to the burner 3.

The side or oven burner 4 is an oblong tubular member of substantially rectangular cross section, which has a series of slots 11 cut in the top and outer side through which the gas is emitted to be bi'irned. A conduit 12 connects the burner 4 at one end with a mixing chamber 13 from whichthe gas is supplied. A tube 14 is supported within the burner-At and is attached to and forms a coritinuation of the conduit 12. The tube 14 is nearly coextensive 'with the interior of the burner, so that it terminates adjacent to the other end of the burner e and serves vto conduct the gas to the farther end of the burner from which it travels back along the space between the burner and the tube and escapes through the slots 11. This tube thus serves to more evenly distribute the gas along the burner and prevent an excessive supply reaching any portion of the slots 11, as would be the case it' the gas entered the connected to the conduit 12.'

The 'enei'ators 5 and (i are refcrabl I in s l the form of tubes and are supported in substantially the same horizontal plane, the

tube 5 being located below the burner 3 and between the arms of the U-shaped pipe 8, and the tube 0 being located above and slightly to one side of the burner 4. The generators are supported by ln ving at one and threaded connections with the oil supply fittings "15 and 16 respectively, and at the opposite ends havin g sliding or telescopic engagement Withthe respective mixing chambers l0 and 13. This permits the .tubes 5 and 6 to he unscrewed from the respective fittings 15 and ill, so asto be quickly rcmovcd from the device for the purpo'a) of cleaning or for replacing new ones. line ends of the tubes 5 and (5 are each provided with an orifice as at 17, Fig. 7, which orifices are located wholly within the respective mixing chambers ll) and 13 and in aliocment with the open ends of the respective conduits 9 and 12. as will be more clearly ohservod from Fig. l.

z-iuxiliary burners 1F? and 19 are arranged adjacent to the respective generators a: and (l. The humor 18 an ohlongz hollow member of substantially inverted T-shaped cross section having slots 18.1 formed in the end of the stem part through which gas is emitted and burned. The burner 18 is supported Within the bend of the U-shaped pipe 8 directly below the generator 5, so that it is adapted to keep the generator heated for the purpose of vaporizing the fuel oil. A

the ends of the generators 5-and 6. These i nipple connection 20 provides coxinnuniew tion with the pipe 8 for the purpose of supplying gas to 'the burner. The. nipple 20 has a seini-i'rylindrical deflector 21 depending therefrom into the U-shaped pipe 8 and opposed to the open end of the conduit 9. This defleotorinsures a sufficient quantity of gas being directed to the burner 18. Channels or troughs 22 are formed in the transverse parts of the burner 18 and are adapted to receive aouantity of oil to be burned for the purpose of preheating-the generator 5 when it is desired to start the operation of the device. A quantity of nonconiluistible absorbent packing may be placed in the troughs 522,

heating.

The auxiliary burner 19 is arranged at one side of the generator 6 between it and the generator 5, and is connected by a nipple 23 to the pipe 8 so that during the operation of the top humor 3, vgas is supplied to the. auxiliary burner 19 whereby the generator 6 is kept sullicicntly heated so that upon the admission of oil to the generator gas will be produced in sufficient quantity to per- The mixing chambers 10 and 13 are in the form of inverted Ls, each having a nipple 26 depending therefrom, which forms the v inlet forair that is to bemixed with the vapor discharged through the orifices 1n Us are supported in place by reason of which is found to improve the burning of the oil for purposes of protheir connection to the generators and the r =s rwtive conduits 9 and 12.

Tile fittings 15 and 16 are connected together by a tube :27 and the former is connected to an oil supply by means of a pipe 2H. Valves 9!) and 30 are managed in the fitting 15 so as to control the supply of oil to the respective generators 5 and 6. The valve 29 has a tapered end 31 which coacts with a seat, for controlling the supply of oil to the generator 5. A rod 33 integrally attached to the valve 2%) and extends longitudinally through the generator 5 and has a needle valve 34: formed on the end thereof which controls the orifice 17. By virtue 01.

this arrangcn'lent oi the valves 2!) and 3-1,

the supply of oil to. the generator 5 and the discharge of vapor therefrom is simultaneously controlled. the usual needle type, as is clearly indi cated injl 'ig. 7. and controls the admission.

opposite ends of said pipe 8. A valve seat.

39 is formed in the burner 3 adjacent to one of the ;openings loading to the pipe, 8 with which a valve 40 coacts for controlling the admission of 'gas from the corresponding end of said pipe to the respective chamber, in this case the chamber 38. A stem 41 car ries the valve 40 and extends to the exterior of the burner and affords means of shifting the valve -10 The device is. intended to he set in the fire box of the stove with the burner facing the partition which separates the fire box from the oven. In order to insure proper spacing of the. burner 4 away from the stove' lining, pins or shoulders 42 protrude from the face of the burner in such manner as to contact with said stove lining.

The operation of the device shownis as follows: To start the device, uipumtity of oil or alcohol is poured into' the .troughs'fl" and ignited, then as it burns it heatsthe generator 5. When the generator 5 has he, comosufiiciently heated, the oil is turned on by means of the .valve 529, so that the oil enters the generator,- whercupon it is converted into a vapor and flows through the orifice 17 into the mixing chamber 10. conduit 9, and ipe 8. On entering the pipe 8, a portion of the gas is deflected by the do .flector .21 into the burner 18, whereby the heating of the generator is continued. The gas also ascends the pipe 8. enters the chants here 3'? and 38 of the burner 3 and is ignited as it is emitted from the slots 7 Byslorting the valve 4 0, one of. the chambem'" may The valve 30 is of operation. The auxiliary biirner 19Qis also gas-from'itheone of the supplied with pipe 8, and the gasfio'wing from; the transverse slot 24- is ignited by the burner 18 r the farther end of the desired to use the :oven

and accordingl i ignites the the slots 25. The 'auxiliary burne'r 19 keeps the generatorfiheated so'thatWhen 'it'is burner 4: it is only necessary to open the the oil to be supplied to the generator 6. By means of the pipe 14,

the gas is conveyed to it passes into the space within the burner 4 surrounding the pipe 14. h f

It is intended that the oven burner 1 4 should be'used only for the purpose of heat- .ingthe'oven to the. proper degree for bak mg, and. when the oven is thoroughly heated and the baking started the oven burner may be shut 0fl'- since thetop burner willmaintain the heat suiiicientlyto finish thebaking. one specific embodimentgof been herein shown and Although but this invention has described, it will be understood that numerous details of the construction shown may be altered or omitted Without departing from the spiritiof this invention 'as defined by the following claims.
